Abstract: Systems, methods, computer-readable medium, vehicles, and engines provided herein include or implement flexible engine monitoring features. In one aspect, a user-modifiable file containing selected parameters is uploaded to a vehicle having a propulsion system, such as an engine. A computing device associated with the engine generates, without modifying reporting software or any other software, a parameter reporting list that includes the selected parameters. During operation, parameter values for the selected parameters are recorded. In another aspect, a data query is transmitted to an aerial vehicle while in-flight. The data query includes a user-modifiable file that contains selected parameters for which parameter values are to be recorded. A computing device associated with the engine generates, without modifying reporting software or any other software, a parameter reporting list that includes the selected parameters.
